IMPROVEMENT IN GRAlN-DRlLLS.

Specification forming part of I etters Patent N oi 46,821, dated March 1},

' lowing to heat full, clear, and exact description thereof, reference being bad tolt'he accompa nyin g drawings, making part of this 'speeifica tion.

My improvement relates to the class of seed-- delivering apparatus of grain-drills which'cou-- -tains a rotary feeder armed with teeth or blades and working in a seed box or cup.;

and the object of my invention is to preventthe cutting and crushing of kernels of grain 1 between the feeder and the ends .or the hottom of the seed-box.

Figure 1 is an axial section through a seeddel'ivering apparatus which embodies myiinprovement. Fig. 2 shows the feeder detached;

Figs.'3, 4, and 5 are. perspective views, and

Fig. Gis an axial section, showing modifieations of my improvement. Fig. 7 is a perspective view of my seed-box and saddle, the feeder and washers being seen in position.. Fig. 8

shows the seed-box and saddlodetached. Fig. Q'shows the seed-box and a portion of the saddle and one of the washers in position. Fig'. 10 is a sectional perspective taken at the line w as, Fig. 8.

A is the seed box or cup, converging toward a rounded bottom, so as to snugly inclose the ends and lower part of the-periphery of a ro-' tary feeder or wallower, B, whose blades or teeth b serve to agitate the seed. and to. discharge it through the ventage a. The feeder B is mounted upon and revolves with a shaft,-

U, which may be a feathered cylinder, as in Fig. 1, or secured by a cotter, as in Fig. 6; or it may have a square or other polygonal section, as in Figs." 1, 2, and 3, in which case it may consist of such rods of iron as may be found ready-made in the stores; nor need the shaft be in one piece, provided the ends meet inside of a feeder, which thus becomes a clutch box or coupling. 4

. In order to prevent the kernels being caught between the feeder and the-ends or bottom of the seed-box, by which so much. grain is crushed and destroyed in seeding apparatus of this class, I'provide -conical, cylindrical, or other smooth and circular washersor collars D, which collars are made to revolve with the faces of the box ends'.

of the seed-box,

shaft and leeder, and occupy circular cavities -or recesses a. in the inner surfaces of the ends of the seed box', the said cavities correspond.-

ing. in depthwith the thickness of the said collars, so as to bring the sides of-.the collars next the feeder flush with the said inner sur- The seed-box may be formed in one piece,

as represented in Fig. 1; but a preferable mode.

of construction is that represented iu Figs. 7 8, ,9, and 10. A. being the cup, and A being a saddle. When the form represented in Fig. 7

is-employed one half of the cavity for the collar isformed in the cupand the other half inthe saddle.

A seed-box thus constructed can at any time be detached fromthe hopper'forinspectiou or repair without withdrawing'the shaft G. The collars, being thus let in or recessed, so as to bring their flat surfaces flush with" those of the cup and saddle, become, in 'efi'ect, revolving Y ends to the seed-box.

'I have selected to illustrate my invention a ,form preferred by me on account of its sim plicity and effectiveness in actual use, but do not desire to restrict the invention to theabove so long as the same results are attained by means substantially equivalent. For example, an octagonal or otherprisma'tic boss upon the feeder may enter a corresponding aperture in the collar, (see Fig. 3;)or-small stiids'a'nd teats entering holes in .the collarniay in like manner'secu're its co-rotaticn .withthe'leeder,.as in Fig. 4; or the dollars may be cast in one-piece with the feeder, as in Fig. 5, and. these-collars" may even come through to the outside of---the box, as in Fig. 6.

' The'ess'ential. features of my improvement are that the collars shall be en tirely circularthat is, free from notches-or.otherjindentations-that theyshall revolve'with the feeder,

and that they shallbe substantially flush with the interior end surfaces of the box. I am aware that co'gged feed-wheels have been proposed having indented or scalloped washers which revolvebetween thefeed-whe'el and the box side, but in such a manner that the peripheries of the washers havebeen exposed within the box orcup, and have been'liable to catch'and crush the kernelsbetween the said peripheries and the cup-bottom, and I there;- fore make no claim to such n01: dol claim collars formed with, notched orsoalloped margins, mechanism; but

so as to constitute apart of the feeding thereof, substantially as and for. the purpose set forth.

What I cla-im herein as new and of my in- In testimony of which invention I hereunto \ention, and desire to secure by Letters Patsetmy hand. ent, is- 1 w The provision in the seed-box of a scalloped BERNARD REGAN or winged feed-wheel 13, having collars D D, Witnesses: occupying recesses a in the ends of the seedhox, so as. to he flush with the inner surfaces GEO.
